## How to create an Issue
Hello!
You may use the Issue Tracker to submit bug reports, feature requests or suggestions. You may ask for help or advice as well. However please read this wall of text before doing so. The amount of incomplete or ambiguous requests due to people not following those guidelines is often overwhelming. Please do your best to clarify your request. Thank you!
**IF YOU ARE HAVING AN ISSUE COMPILING/LINKING/RUNNING/DISPLAYING/ADDING FONTS/WIRING INPUTS**
- Please post on the "Getting Started" Discourse forum: https://discourse.dearimgui.org/c/getting-started
**Prerequisites for new users of dear imgui:**
- Please read the FAQ in imgui.cpp.
- Please read misc/fonts/README.txt if your question relates to fonts or text.
- Please run ImGui::ShowDemoWindow() to explore the demo and its sources.
- Please use the Search function of GitHub to look for similar issues. You may also browse issues by tags.
- Please use the Search function of your IDE to search in the code for comments related to your situation.
- If you get a assert, use a debugger to locate the line triggering it and read the comments around the assert.
**Guidelines to report an issue or ask a question:**
- Please provide your imgui version number.
- Please state if you have made substantial modifications to your copy of imgui.
- Try to be explicit with your Goals, your Expectations and what you have Tried. What you have in mind or in your code is not obvious to other people. People frequently discuss problems without first mentioning their goal.
- If you are discussing an assert or a crash, please provide a debugger callstack. Never state "it crashes" without additional information. If you don't know how to use a debugger and retrieve a callstack, learning about it will be useful.
- Please make sure that your compilation settings have asserts enabled. Calls to IM_ASSERT() are scattered in the code to help catch common issues. By default IM_ASSERT() calls the standard assert() function. To verify that your asserts are enabled, add the line `IM_ASSERT(false);` in your main() function. Your application should display an error message and abort. If your application report an error, it means that your asserts are disabled. Please make sure they are enabled.
- When discussing issues related to rendering or inputs, please state the OS/back-end/renderer you are using. Please state if you are using a vanilla copy of the example back-ends (imgui_impl_XXX files), or a modified one, or if you built your own.
- Please provide a Minimal, Complete and Verifiable Example ([MCVE](https://stackoverflow.com/help/mcve)) to demonstrate your problem. An ideal submission includes a small piece of code that anyone can paste in one of the examples/ application (e.g. in main.cpp or imgui_demo.cpp) to understand and reproduce it. Narrowing your problem to its shortest and purest form is the easiest way to understand it. Please test your shortened code to ensure it actually exhibit the problem. Often while creating the MCVE you will end up solving the problem! Many questions that are missing a standalone verifiable example are missing the actual cause of their issue in the description, which ends up wasting everyone's time.
- Try to attach screenshots to clarify the context. They often convey useful information that are omitted by the description. You can drag pictures/files here (prefer github attachments over 3rd party hosting).
- When requesting a new feature, please describe the usage context (how you intend to use it, why you need it, etc.).
**Some unfortunate words of warning**
- If you are or were involved in cheating schemes (e.g. DLL injection) for competitive online multi-player games, please don't post here. We won't answer and you will be blocked. We've had too many of you.
- Due to frequent abuse of this service from aforementioned users, if your GitHub account is anonymous and was created five minutes ago please understand that your post will receive more scrutiny and incomplete questions may be dismissed.
If you have been using dear imgui for a while or have been using C/C++ for several years or have demonstrated good behavior here, it is ok to not fullfill every item to the letter. Those are guidelines and experienced users or members of the community will know which information are useful in a given context.
## How to create an Pull Request
- Please understand that by submitting a PR you are also submitting a request for the maintainer to review your code and then take over its maintenance forever. PR should be crafted both in the interest in the end-users and also to ease the maintainer into understanding and accepting it.
- When adding a feature, please describe the usage context (how you intend to use it, why you need it, etc.).
- When fixing a warning or compilation problem, please post the compiler log and specify the version and OS you are using.
- Try to attach screenshots to clarify the context and demonstrate the feature at a glance. You can drag pictures/files here (prefer github attachments over 3rd party hosting).
- Make sure your code follows the coding style already used in imgui (spaces instead of tabs, "local_variable", "FunctionName", "MemberName", etc.). We don't use modern C++ idioms and can compile without C++11.
- Make sure you create a branch for the pull request. In Git, 1 PR is associated to 1 branch. If you keep pushing to the same branch after you submitted the PR, your new commits will appear in the PR (we can still cherry-pick individual commits).
Thank you for reading!

This affects clamping window within the visible area: with this option enabled title bars need to be visible. (#899)
- Window: Fixed using SetNextWindowPos() on a child window (which wasn't really documented) position the cursor as expected
in the parent window, so there is no mismatch between the layout in parent and the position of the child window.
- InputFloat: When using ImGuiInputTextFlags_ReadOnly the step buttons are disabled. (#2257)
- Error recovery: Extraneous/undesired calls to End() are now being caught by an assert in the End() function itself
at the call site (instead of being reported in EndFrame). Past the assert, they don't lead to crashes any more. (#1651)
- Error recovery: Missing calls to End(), pass the assert, should not lead to crashes or to the fallback Debug window
appearing on screen, (#1651).
- IO: Added BackendPlatformUserData, BackendRendererUserData, BackendLanguageUserData void* for storage use by back-ends.
- Style: Tweaked default value of style.DisplayWindowPadding from (20,20) to (19,19) so the default style as a value
which is the same as the title bar height.

PROGRAMMER GUIDE
================
READ FIRST
READ FIRST:
- Read the FAQ below this section!
- Your code creates the UI, if your code doesn't run the UI is gone! The UI can be highly dynamic, there are no construction
or destruction steps, less superfluous data retention on your side, less state duplication, less state synchronization, less bugs.
- Call and read ImGui::ShowDemoWindow() for demo code demonstrating most features.
- You can learn about immediate-mode GUI principles at http://www.johno.se/book/imgui.html or watch http://mollyrocket.com/861
See README.md for more links describing the IMGUI paradigm. Dear ImGui is an implementation of the IMGUI paradigm.
- The library is designed to be built from sources. Avoid pre-compiled binaries and packaged versions. See imconfig.h to configure your build.
- Dear ImGui is an implementation of the IMGUI paradigm (immediate-mode graphical user interface, a term coined by Casey Muratori).
You can learn about IMGUI principles at http://www.johno.se/book/imgui.html, http://mollyrocket.com/861 & more links docs/README.md.
- Dear ImGui is a "single pass" rasterizing implementation of the IMGUI paradigm, aimed at ease of use and high-performances.
For every application frame your UI code will be called only once. This is in contrast to e.g. Unity's own implementation of an IMGUI,
where the UI code is called multiple times ("multiple passes") from a single entry point. There are pros and cons to both approaches.
- Our origin are on the top-left. In axis aligned bounding boxes, Min = top-left, Max = bottom-right.
- This codebase is also optimized to yield decent performances with typical "Debug" builds settings.
- Please make sure you have asserts enabled (IM_ASSERT redirects to assert() by default, but can be redirected).
If you get an assert, read the messages and comments around the assert.
- C++: this is a very C-ish codebase: we don't rely on C++11, we don't include any C++ headers, and ImGui:: is a namespace.
- C++: ImVec2/ImVec4 do not expose math operators by default, because it is expected that you use your own math types.
See FAQ "How can I use my own math types instead of ImVec2/ImVec4?" for details about setting up imconfig.h for that.
However, imgui_internal.h can optionally export math operators for ImVec2/ImVec4, which we use in this codebase.
- C++: pay attention that ImVector<> manipulates plain-old-data and does not honor construction/destruction (avoid using it in your code!).
HOW TO UPDATE TO A NEWER VERSION OF DEAR IMGUI
HOW TO UPDATE TO A NEWER VERSION OF DEAR IMGUI:
- Overwrite all the sources files except for imconfig.h (if you have made modification to your copy of imconfig.h)

Q: How can I easily use icons in my application?
A: The most convenient and practical way is to merge an icon font such as FontAwesome inside you

You may want to see ImFontConfig::GlyphMinAdvanceX to make your icon look monospace to facilitate alignment.
